Simple source code control app

[Pteranodon]

I'm looking for a simple source-code control app, not VSS, preferably free. I mostly need it for revision control, etc. It doesn't need to have fancy stuff like security or multiple-developer support. Any ideas?

What is wrong with VSS?

Here are some things that Googled returned.

My last experience with VSS was not a good one, so I uninstalled it.

I'm wondering if anyone has experience with any of the Google results.

I use VSS but there is also SVN/Subversion (upgrade of the popular CVS app) which I believe is the largest open source one used. It's not bad and it's free, and you can get downloads such as tortoise SVN which install Windows explorer interaction features (so you right click on a folder or file and choose upload (or commit in this program's case).

EDIT: after reading penagate's note below, this can be inplemented on win/*nux platforms I believe also.
